Answer:

120,000

Explanation:

To estimate the product of 283 × 416, first round each number so that each number contains only 1 non zero digit.

In this case, we will round 283 to the nearest hundred and we will also round 416 to the nearest hundred. To round 283 to the nearest hundred, the number next to two is higher than 5 so we round up. 283 rounds to 300.

416 rounded to the nearest hundred is 400 because the digit to the right of 4 is less than 5 which means we round down. 416 rounds down to 400.

Now we have 300 × 400 which equals 120,000

This means that 283 x 416 is approximately 120,000.
